Abstract Resume

Background: Sport climbing is the new indicated sport for the Olympic Games in Tokyo 2020 and its comprehension and characterization is an eminent need. Sport Climbing can be divided
into two courses. The Route Difficulty (RD) is practiced in long walls using ropes for safety, and the goal is to reach the top without any falls. This type of climbing is characterized by greater
duration and moderate intensity and the athlete to perform small moments of active rest during your climb. In competitions, the RD athletes attempt to perform an established route that is
unprecedented. Bouldering (BD) is practiced in small and undertaken without ropes, with landing mats to ensure safety. This type of climbing is characterized by shorter duration and high intensity
and does not allow moments of active rest during your climb. In BD competitions, climbers attempt to top unprecedented problems and may make several attempts to complete the route within 4 minutes
each. Thus, as the performance demands differs among each type of climbing, physical, technical and tactical features may also be specific as function of the type of climbing and should be described
accordingly. Thus, the aim of this study is to compare anthropometric variables between RD and BD climbers. We hypothesize that the anthropometric profile may differ between each type of climber.
Methods: The measures were performed in the male athletes participating the Brazilian RD and BD Championships. We assessed 22 of the 23 RD competitors (age 28.0 ± 6.0; time climbing
10.0 ± 4.6) and 15 of the 29 BD competitors (age 25.0±6.1; time climbing 7.3 ± 4.3). The body composition variables were assessed using electrical bioimpedance quadrupole scale (Beurer BF-100®). The
athletes were instructed to be bladder empty before the collections. To measure their height, arm and forearm circumference we used a portable estadiometer and a measuring tape fixed on the wall,
respectively. After testing data normality using Lilliefors test, all variables were compared as function of the type of climbing using Wilcoxon rank sum test, with P ≤ 0,05.
Results: We observed a tendency to significant differences for percentage of lean body mass (RD 46.7±3.3 vc BD 48.3±10.1 P= 0.06) and percentage of body fat (RD 9.7 ± 2.9 % vs BD 8.0
± 2.2 % P= 0.06). No differences were found for weight (RD 64.5 ± 8.0 kg vs BD 63.3 ± 7.6 kg), height (RD 174.6 ± 6.8 cm vs BD 172.1 ± 6.5 cm), index body mass (RD 20.8 ± 1.6 vs BD 21.2 ± 1.5), arm
(RD 31.9 ± 2.1 cm vs BD 30.9 ± 3.5 cm) and forearm circumferences (RD 27.4 ± 1.6 cm vs BD 28.3 ± 2.4 cm
Conclusions: We conclude that bouldering and difficulty route Brazilian athletes do not show significant differences in anthropometric characteristics but bouldering athletes tend to
have higher lean body mass
